    Will the external thunderbolt powered gpus use the internal screen? Or will you need to use an external monitor? Talking about things that are coming out like the sonnet express.

    Thanks!

    Not sure. I would hope you can do it with the 13" since it does not have a dedicated card already installed. ( I run an Optimus configuration with an eGPU on one laptop on the internal display now )

    as for the 15" and 17" with a second card already there you would need to set up IGP and 2 dedicated cards so a much greater possibility of it not working.

    but alas this is just a guess and we wont have an honest answer until it is actually out.

    All of the current mbp have muxes, including the 13 (strange huh?)

    So it could be possible that you could play it on the laptop screen. However as KCetech said we wont know until the egpu solutions have come out

    not strange at all, the base multiplexor is built into the SB architecture. EVERY SB laptop has one MUX ... some even have 2

    in the IGP actually ( so technically the northbridge chipset ). and was actualy the cause of many issues with Optimus graphics switching a year ago with pro applications having massive OpenGL issues since the IGP mux and the software calls were trying to use the same resources.
